Script takes a while to detect another part, how do I make it faster?

This script is inside a part that detects other parts and see's whether or not the name of the part it's detecting is valid. If the part's name is valid then it will be unanchored and fall through the map. What I'm trying to do is make the script not have any delays when detecting the parts so it'll just check any part and unanchor it quickly. I'm not sure what to do now but if anyone has any suggestions I would really appreciate!

local childList = {}
local Min = 0
while true do
function checkObject(obj)
    if (obj ~= script.Parent) and (obj.Name == "Breakable")  then
            table.insert(childList,obj)
elseif (obj.className == "Model") or (obj == workspace) then
        local child = obj:GetChildren()
        for x = 1, #child do
            if child[x].ClassName == "Model" then
                checkObject(child[x])
            elseif child[x].Name == "Breakable" then
                table.insert(childList,Min,child[x])
            end
        end
        obj.ChildAdded:connect(checkObject)
    end
    end
checkObject(workspace)
    if Min < #childList then
    Min = Min + 1
    wait()
    else
        Min = 1
        wait()
    end
    local child = childList[Min]
    if (child ~= script.Parent) then
        local dis = (child.Position-script.Parent.Position).magnitude
        if dis <= 200 then
            child.Anchored = false
            child.CanCollide = false
            table.remove(childList,Min,child)
            Min = Min - 1
            wait()
        end
        wait()
    end
    wait()
        end
